DEX450: Build Applications Programmatically on the Salesforce Platform Course Outline
Overview
Who should take this course?
This course is designed for programmatic developers looking to write programmatic customizations to both business logic and UI layers using Apex and Visualforce. You should have a good understanding of core object-
oriented programming concepts and experience building declarative solutions on the Salesforce Platform. This course is also a great foundation builder if you’re looking to earn your Salesforce Platform Developer I credential.
When you complete this course, you will be able to:
- Learn modern tools for developing on the Salesforce Platform using Visual Studio Code, the Salesforce Extension Pack, and the Salesforce CLI.
- Write business logic customizations using Apex triggers and classes; those customizations will use SOQL and DML.
- Design programmatic solutions that take advantage of declarative customizations.
- Describe how your trigger code works within the basics of the Save Order of Execution.
- Describe some of the fundamental aspects of designing programs on a multi-tenant platform.
- Write Visualforce markup and code to customize the user interface.
- Use the built-in testing framework to test Apex and Visualforce.
